Abstract

FIELD: technology of production of dry reducible nutritious mixtures for functional alimentation. SUBSTANCE: method involves mixing of fat-, protein- and carbohydrate-containing components, and mineral and enzyme additives. Prepared mixture is impregnated by miscella in alternating magnetic field under increased pressure. Miscella is prepared in the process of extraction of biomass of Mortierella gracilis micromycete with nonpolar extracting agent under above-critical condition, then pressure is relieved up to atmospheric one. EFFECT: increased stability of final product during storage life.

Description

 The invention relates to a technology for the production of dry reconstituted nutritional mixtures for functional nutrition.

 There is a method of producing a nutrient mixture for baby, dietary or intestinal tube nutrition, which involves drying and mixing fat, protein and carbohydrate-containing components, mineral and enzyme additives, impregnation with liquefied gas under high pressure and depressurization to atmospheric (RU 2035879 C1, 27.05. 1995).

 The disadvantage of this method is the syneresis of fat of the target product during storage.

 The technical result of the invention is to increase the resistance of the target product to storage.

 This result is achieved by the fact that in the method of producing a nutritional mixture for baby, dietary or intestinal tube nutrition, which involves drying and mixing fat, protein and carbohydrate-containing components, mineral and enzyme additives, impregnation with pressure medium and depressurization to atmospheric pressure, according to miscella obtained by extraction of biomass of micromycete Mortierella gracilis with a non-polar supercritical extractant is used as the pressure medium, and implemented at a variable magnetic field.

 The method is implemented as follows.

 Fat, protein and carbohydrate-containing components intended for the production of the target product are dried and mixed with mineral and enzyme additives. The biomass of micromycete Mortierella gracilis is extracted with a non-polar extractant, for example, aliphatic hydrocarbons, carbon dioxide, nitrogen, nitrous oxide, inert gases, in the supercritical state. Extractants of this type extract from the said biomass mainly higher fatty acids, which are mainly polyunsaturated in the selected micromycete. Miscella is removed from the extraction stage without changing physical parameters and without separating the extract and extractant, respectively, and then sent to the impregnation of the resulting mixture. The impregnation is carried out in an alternating magnetic field, which contributes to the intensification of mass transfer in the resulting mixture. The supercritical non-polar extractant dissolves the high molecular weight lipids of the mixture during the impregnation process, which contributes to their most uniform distribution throughout the volume. After the impregnation is completed, the pressure is released to atmospheric. This leads to explosive grinding of the components of the mixture with the destruction of the cell walls of both the components of biological origin and microflora. In this case, lipids dissolved in the extractant are released from the miscella and distributed throughout the mixture. This also makes it easier to access enzymes that maintain activity to digestible biopolymers of the components of the mixture and reduce the allergic reaction to taking the mixture. The resulting mixture is Packed under aseptic conditions in consumer packaging. During storage of the mixture during the warranty period, no fat syneresis was detected.

 It should be noted that the biomass extract of micromycete Mortierella gracilis introduced into the mixture enriches its composition with substances that have F-vitamin activity, which increases the quality of the mixture and increases its shelf life due to the antioxidant activity of these substances. In addition, these same substances are stabilizers of consistency and prevent delamination of the mixture reconstituted before use, which is especially important when it is used in probe nutrition.

 Thus, the proposed method allows to increase the durability of the target product during storage.
